alternative for JBL Control Now AW as outdoor speaker (+propber amplifier)

Hallo,
I have a medium size balcony ~16mē but half of it is covered by the upper flat. Now I intend to sound it a bit. At my researches I found the Control Now AW from JBL , which has a outstanding design unfortunately not that cheap for only 16mē.
Does anyone know an alternative?
Furthermore that is a passive speaker, so I need an amplifier, so do you know a weatherproof amplifier, else it gonna be 3..2..1..my-> ebay
